PATENT MOBILE APPARATUS FORPREPARATIUN F HOT-WATER DRES SINGS OFFICE amended April 30, 1928; 376 O.G. 757) The invention described herein may be manufactured and used byor for the Government for governmental purposes, without payment to meof any royalty thereon.

This invention relates generally to a portable heating device but moreparticularly to an apparatus for the preparation of hot water packs ordressings as used by physicians and nurses in the treatment ofpoliomyelitis and other ailangularly arranged standards is attached aspider 2!, and the standards are mounted on casters 2 l so that theframe may be easily rolled around from place to place.

Upon the floor l5 of the platform I6 is mounted an electric stove 22.The legs 23 of the stove are adapted to fit within seats formed in thefloor It. The stove is provided with a switch 24 through which theheating elements thereof (not ments. shown) are connected throughconducting leads One object of the invention is to provide an 25 to awall plug 26, so that the device may be e e c y heated Vessel Which y bereadily plugged into the nearest or most convenient outmoved from placeto place in a hospital, surlet for electrical energy.

Inoperating the wringer the Wet porting ring 20*. To the lower portion ofthe tri cloths are held by one end between the rollers which are keptseparated by the spring 43. The operator then pushes the treadledownwardly with his foot and moves the rollers toward each other. Whenthe rollers are contacting the wet cloth with sufficient pressure theoperator turns the crank handle 42 to move the cloth between the rollersand thus press out the water absorbed thereby. The cloth may be releasedfrom the pressure of the rollers at any time by simply raising the footfrom the treadle so that the spring will move the roller 33' out ofengagement with the cloth.

Having thus described my invention, what I claim as new and wish tosecure by Letters Patent is:

A device for preparing hot water packs comprising a frame composed of aplurality of uprights, a combined supporting and suspension ringconnected to said uprights at their upper extremities, a spiderconnected to the lower portion of said uprights, a platform supported bysaid uprights above said spider, a source of heat mounted upon saidplatform, a heating vessel REFERENCES CITED The following references areof record in the file of. this patent:
